This page is devoted to describing the
SimDB data model (SimDB/DM from now on).
Current model
As described
here all development can be followed on Volute.
Particularly relevant for the discussion on this page is the data model in
uml/SimDB_DM.xml.
The previous versions as well as later working versions can be found in the history of this file, as well as its direct predecessor
version r902.
An image of the latest version of the model is reproduced at the bottom of this page.
To be discussed
- OK on approach?
- modelling: analysis(conceptual)->logical->physical
- TAP+XML+UTYPE serialisations derived from logical model
- Identify main issues of model
- sufficiently detailed resources?
- characterisation
- normalisation (problem for XML, little for TAP)
- "queriability" (problem for TAP)
- missing semantic vocabularies
- quantities/units
- Clean up
- documentation in the UML
- Description of model in Note
- finalise the serialisation to UTYPEs
- finalise the serialisation to TAP (see IVOA.IVOATheorySimDBTAP)
- finalise the serialisation to XML schema ((see IVOA.IVOATheorySimDBREST)
- reuse by other specs
- ...
